many times, OD and OE errors are referring back to memory or processor issues.
and I mean memory issues could be hardware or software caused.
but the easiest thing to do would be to reseat your system ram, reseat your processor, make sure there isn't a lot of dust in/on/near either.. (especially the CPU and its fan.. make sure its spinning freely if so equiped)
If this doesn't fix the issue, and you've not tried the drive formats, try it again..
Also.... have you tried SAFE MODE .. since you're getting a BLUE screen, that suggests the OS *IS* loading... other wise, you would normally have a black screen with white writing and it would identify memory addresses, or possibly state *parity error* ...
To force the system to giveyou the boot menu,...
power on the system
press and hold the LEFT control key. You should *not* get a key stuck error, and just after the verifying DMI you should get your win98 boot menu.
try Safe Mode
If plain safe mode doesn't work
try Safe Mode with Confirmation
selectively answer yes to EACH individual item. When you get your blue screen, remember the item you last said yes to, then reboot and this time say NO .. see if it continues to load for you
